Black = running rich (carb/fuel inj.); blue = oil (rings, bad PCV valve, or valve seals); steam/sweet smell = antifreeze (head gasket or cooling system leak).
Do compression test of cylinders and pressure test of cooling system. That should give you a direction to head.
Can't estimate $$$ until you know what is wrong (could be $3 - $300).
